Electronics Integrated Circuits Product Number : AD5697R
Integrated Circuits (ICs)Total unadjusted error (TUE): ±0.1% of full-scale range (FSR) maximum Offset error: ±1.5 mV maximum Gain error: ±0.1% of FSR maximum
The AD5697R, a member of the nanoDAC+™ family, is a low power, dual, 12-bit buffered voltage output digital-to-analog converter (DAC). The device includes a 2.5 V, 2 ppm/°C internal reference (enabled by default) and a gain select pin giving a full-scale output of 2.5 V (gain = 1) or 5 V (gain = 2). The AD5697R operates from a single 2.7 V to 5.5 V supply, is guaranteed monotonic by design, and exhibits less than 0.1% FSR gain error and 1.5 mV offset error performance. The device is available in a 3 mm × 3 mm LFCSP and a TSSOP package. The AD5697R also incorporates a power-on reset circuit and a RSTSEL pin that ensure that the DAC outputs power up to zero scale or midscale and remain there until a valid write takes place. It contains a per channel power-down feature that reduces the current consumption of the device to 4 µA at 3 V while in power-down mode. The AD5697R uses a versatile 2-wire serial interface that operates at clock rates up to 400 kHz and includes a V LOGIC pin intended for 1.8 V/3 V/5 V logic. Rev. A
